CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 741,032, dated October 13, 1903. Application filed April Z, 1902, Serial No. 101,108. (No model.)

of car-seat structure disclosed in Letters Pat out No. 692,183 and granted to me on January 28, 1902, and consist more particularly in a modification of the main framework of pressed steel.

The object of my invention is to produce a pressed-steel construction of car-seat framework which shall be simpler, cheaper, and more satisfactory than the structure shown in the aforesaid patent, and said objects are secured by the structures more particularly described hereinafter.

In carrying out my invention I provide a pressed-steel end frame with end flanges and an upper curved flange which acts as a guide for supporting and guiding the seat-backcarrying arms, the said upper curved edge being preferably formed of double thickness by doubling the metal of the flange upon itself. This end frame may be combined with the pedestal portion, formed of two parts riveted or otherwise secured together to constitute a hollow pedestal and which pedestal may be integral with the end frame or connected with it by an adjustable con the longitudinal connecting bars with part broken away. Fig. 5 is an inside elevation of the end frame andpedestal when formed with improvements for vertical adjustment. Fig. 6 is a sectional plan View of same on 6 6 of Fig. 5, and Fig. 7 is a cross-section showing how the two metal parts of the pedestal may be united.

Y Ais the end frame and is formed of stamped sheet metal with the ends flanged, as at B, and the upper part flanged, as at O, on a curve of large radius. This upper. flange C is preferably made of double thickness'by having the metal bent over upon itself, as indicated at c in Fig. 2,510 as to give greater thickue ssboth for strength and for wear and also to give a smooth surface to the inner edge.

In my former patent the end frame was made with flanges all around and a curved guide for supporting the seat-back either forced up on the inner face or riveted upon the said face. I have found these constructions expensive and undesirable on the ground that they required the area of the end frame to be greater than Was convenient to be received in the mortised wooden frame carrying the arm-rests. In my present construction I do away with the upper part of the end frame as formerly made and form the curved guide directly upon the upper edge or flange, thereby reducing the area of the frame, securing the curved guide as an integral structure with the end frame, cheapening the cost of manufacture, and lighteningthe weight of the structure. On the aisle end of the seat the arm-rest frame L, of wood, is secured to the outer surface of the end frame A; but on the window end of the seat there is usually cured together, as at d, constitutes a pedestal E, having a flaring base 6, as shown. If

desired, the part D may be omitted'and the other semi-elliptical portion connected to the end frame otherwise than bybeing formed integral therewith. While I prefer to form the pedestal or a portion of same integral with the end frame A, it is evident that the novelty of the structure of the end frame would be the same even if the pedestal were omitted, as is usually the case at the window end of the seat.

F represents the longitudinal bars for connecting the end frames of said structure and are preferably formed of angleiron, having notches f upon one of the edges for guiding the seat-supporting frame H. These angleiron bars may be conveniently attached in place by slotting them transversely, as at F, and. bending over the end to form the flange F which is firmly held in place by the rivets F through the lower portions of the bar, as is clearly shown in Figs. 1, 2, and 4. However, any other form of longitudinal bars may be employed, if desired, in lieu of that here shown. The ends of these bars are supported upon inwardly-projecting portions O of the end frame A and are bolted or riveted thereto, as desired. The inwardly-projectingiportions 0, aside from imparting strength, produce recesses upon the outer surface for the reception of the rivet or bolt heads, so as to enable the woodwork L to fit up fiat against the outer surface of seat end frame. There is an end frame at each end of the seat, and its bars F and both ends of the structure are the same, except that usually the inner end frame is secured against the wall of the car in place of being supported upon a pedestal.

The seat-supporting frames H may be of any suitable construction, that shown being Well adapted for the purpose and in this case being of cast metal with the cam-surfaces h and with the downwardly-directed slot 70 at the center. The seat-cushion G is sustained upon a seat-supporting frame H at each end of the seat.

The seat-back is secured to the supportingarms M, which are flared at the bottom and provided with laterally-projecting guide-lugs P, forming sockets to fit over the edge of the curved guide 0 upon the upper edge of the end frame. These arms M are further provided with a slot 'm, in which a pin or roller Nworks, said pin or roller being secured to the end of the upper arm of the lever J, which is secured to the rock-shaft I and has its lower -and shorter arm projected downward and furnished with a pin or roller K, working in the slot of the seat-supporting frame H, for the purpose of shifting it. It will be seen that after the back is shifted from the right to left in Fig. 1 the seat-cushion will be shifted simultaneously in the opposite direction and at the same time lifted upward at its forward end by means of the cam action between the parts h of the frame H, and fof the bars F. The end of the rock-shaft I is received in a hole in one of the depressed portions 0 of the end frame, as in the case of the rivets or bolt-s where the bars F are attached, so as to provide a space on the outside in which the end of the shaft may project to avoid the possibility of the shaft springing out of the hole,because of too short a bearing.

In case it is'desired to supply the end frame A with provision for vertical adjustment relatively to the floor this may be accomplished by making the pedestal E extensiblefor example, in the manner shown in Figs. 5 and 6. In these figures the pedestal is made of two parts riveted together, as has been described; but in this case the body part D 'is made tubular. The lower part of the end frame is provided with an extension D formed by bending the metal into tubular shape, so as to just fit the tubular part D of the pedestal. The adjoining edges of the metal of the top part D are abutted and connected by an internal piece, as shown. The two parts D and D may be connected together at proper adjustment by rivets or bolts R, extending through the parts D and holes 1' of the part D The particular height of the pedestal is previously determined upon and the parts D, r, and D securely fastened together in proper relative position before the seat is set up. The adjustability of the height of the pedestal or seat may be accomplished in any other convenient manner, my invention comprehending generically the vertical adjustment of the pedestal or seat to support the seat-cushion at the proper distance desired from the floor.

While I prefer the construction herein shown, the details thereof may be modified without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
